| Abstract | In many fields of active noise control (ANC), the filtered-x least mean squares (LMS) algorithm and its relatives such as MELMS (Multiple Error LMS) are popular ones. In these algorithms, the input signal to the algorithms is the signal filtered by the plant model, which must be identified in advance. As well known, the usage of the filtered signal causes two major problems: the delay introduced to the signal path; the well known eigenvalue spread in the autocorrelation matrix. In this article, the multichannel active noise control is proposed for specific applications such as ventilation equipment and ANC inside cars. The reference signal is decomposed into plural narrow-band signals by estimating each resonant frequency. As this approximation leads to that frequency characteristics of the plant model around vicinity of resonant frequencies are only taken account, there is no need to identify the overall characteristics of the plant model in advance. In the proposed method, lower order adaptive filters are only needed to adjust to the plant model with on-line manner. Finally, it is shown that the proposed method has almost the same performance as the MELMS algorithm with much less computational load. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
